    What are titanium tubes used for?

    2023-02-09

    We need to know the characteristics of titanium before using it. First, titanium has low density, which is half of stainless steel, so the weight of titanium is only half of stainless steel with the same volume, and it greatly reduces the weight. Second, titanium has better corrosion resistance to salt water (sea water) than copper. The titanium alloy materials such as Ti-3Al-2.5V, Ti-6Al-4V have the above advantages, and they also have higher strength and hardness. Titanium tube is a metal material with high strength, hardness and corrosion resistance, which is widely used in aerospace, chemical corrosion prevention, health care, marine engineering equipment, refrigeration and heat transfer, bicycle and wheelchair frames, etc. With the development of science and technology, titanium tube is used more and more widely in many fields. 1. Aerospace field Titanium tube used in aerospace field must have high strength and hardness, good creep resistance, high tensile strength at high temperature, and also certain corrosion resistance. The main titanium alloy material used is Grade 9(Ti-3Al-2.5V). AMS 4943, AMS4944, AMS4945 standards are implemented. 2. Chemical corrosion prevention field Titanium tube can be used in acid and alkali environment, but not usable in sulfuric and nitric acid environment. Chlor-alkali industry specializes in producing chlorine gas and caustic soda by electrolyzing salt aqueous solution. As the earliest, chemical industry that uses titanium, it has a history of more than one hundred years. The main titanium equipment used in chlor-alkali production is metal anode electrolytic cell, ion-film electrolytic cell, tubular wet chlorine cooler, refined brine preheater, dechlorination tower, chlor-alkali cooling scrubber, vacuum dechlorination pump and valve, etc. Titanium tube can be used in the temperature of -50℃~+250℃. but cannot be used in higher temperature and extremely cold environment. Commercial pure titanium is the main material used. 3. Health care field Since titanium tube is harmless to human…

    Titanium Tubing on Bicycle Frame

    Why Seamless 3AL-2.5V Titanium Tubing ? In addition to unalloyed titanium, which is called commercially pure or CP, there are two alloys commonly used in the cycling industry today: 3AL-2.5V and 6AL-4V. CP has half the strength of 3-2.5. A CP frame must be made heavier than an equivalent 3AL-2.5V frame in order to have comparable strength. Even most steels used in high quality frames have higher strength than CP. 6AL-4V tubes are not seamless. only heavy thickness tubes, 6/4 titanium has a greater tensile strength but it’s very hard to weld. they are rolled from a sheet and welded at the joint. What does that mean? It means that there is a potential failure point at the welded seam. Therefore, we don’t recommend using this type of tubing. 3AL-2.5V titanium is an alloy consisting of 3% aluminum, 2.5% vanadium, and 94.5% pure titanium. The properties critical to bicycle tubing are best served by a high quality 3-2.5 seamless tube. Excellent fatigue life, property consistency, formability, and corrosion resistance are but a few of the reasons 3-2.5 is still the premier frame material. Nothing Looks Like Titanium Tubing The unique performance of titanium material makes it an excellent material for making bicycle frame. Its high strength, low density, low elastic modulus, excellent fatigue resistance and corrosion resistance make the titanium alloy frame made not only very strong and durable, but also very light. Titanium does not break, rust, or corrode in any atmospheric environment. Titanium is so resistant to corrosion that it doesn’t even need any paint treatment. We just lightly rub the surface to brighten up its natural color. Nothing Rides Like Titanium Tubing Titanium, like steel, has an inherent flexibility, but it’s more pronounced. As a result, it has a very slight elasticity, which means it can absorb…
